How can you use “circannual” in a sentence? Here are some example sentences to help you improve your vocabulary:

These results have implications for studies on F344 and other photoperiodic strains of rats, particularly because the F344 rat is widely studied throughout the world, and has been the most commonly used inbred rat strain in the United States [ 32 ] . The existence of both reproductive and nonreproductive responses of adult F344 rats to short photoperiod, and the possibility for weak endogenous circannual responses to short photoperiods could complicate the design and interpretation of experimental results, especially in the case of long-term studies.
Endogenous circannual rhythms may serve to protect the timing of seasonal functions from noise in environmental cues [ 2 ] , and may improve seasonal timing by buffering variation in the detection or measurement of even the most reliable environmental cues, including photoperiod.
These weeks represented times at which minimum and maximum SD LH levels should have occurred based on examination of testis volume levels at these weeks, if an endogenous circannual LH rhythm existed.
However, the results provided only weak evidence for an endogenous circannual rhythm in the reproductive system.
Here we report that adult F344 rats retain both reproductive and nonreproductive responses to short photoperiod, and that there is weak evidence for an endogenous circannual rhythm of reproductive responses to short photoperiod in F344 rats, but not such a rhythm for non-reproductive responses to short photoperiod.
